Question

A 60 kg box is pushed horizontally across the floor a distance of 20 meters. The force required is 15 N. In this effort, how many joules of work are done?

Answer 1

Answer: 300 J

Step-by-step explanation:

The Work
`W` done by a Force
`F` refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path with distance
`d`.

When the applied force is constant and the direction of the force and the direction of the movement are parallel, the equation to calculate it is:

`W=(F)(d)` (1)

Where:

`F=15 N`

`d=20 m`

`W=(15 N)(20 m)` (2)

`W=300 Nm=300 J` (3) This is the Work (taking into account
`1J=(1N)(1m)=Nm` )
